本文介绍了如何在WPF中实现文本格式化，通过在Window_Loaded事件中设置TextBlock对象的FontSize、Inlines属性，创建不同样式的文本，如斜体、粗体和加粗斜体，同时展示了TextBlock类及其继承关系。

前台：默认即可

<Window x:Class="FormatText.Window1"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="FormatText" Height="300" Width="300" Loaded="Window_Loaded">
    <Grid>
    </Grid>
</Window>

后台：Window_Loaded(object sender,RoutedEventArgs e)事件中代码

 	   Title = "Format the Text";

            TextBlock txt = new TextBlock();
            txt.FontSize = 24;              // 24

            txt.Inlines.Add("This is some ");

            txt.Inlines.Add(new Italic(new Run("italic")));
            txt.Inlines.Add(" text, and this is some ");

            txt.Inlines.Add(new Bold(new Run("bold")));
            txt.Inlines.Add(" text, and let's cap it off with some ");

            txt.Inlines.Add(new Bold(new Italic(new Run("bold italic"))));
            txt.Inlines.Add(" text.");

            txt.TextWrapping = TextWrapping.Wrap;

            this.Content = txt;

TextBlock 类包含在System.Windows.Controls 命名空间内，但Inlines属于System.Windows.Documents

命名空间。具体的继承关系如下：

Object

    DispatcherObject (abstract)

           DependencyObject

                 ContentElement

                        FrameworkContentElement

                               TextElement (abstract)

                               Inline (abstract)

                                      Run

                                      Span

                                            Bold

                                            Hyperlink

                                            Italic

                                            Underline
